Besides Jimmy Stewart the main thing I love about this movie is that they kept the Hungarian character names and signage when adapting for Hollywood. The boss thinks Jimmy is sleeping with his wife and fires him, but fellow salesman Joseph Schildkraut was the cheater, and the boss’s suicide is foiled by the errand boy. This all leads to some holiday season personnel-shuffling in the shop, and in the final couple seconds, romantic penpals Margaret Sullavan and Jimmy finally get together. The boss was the actual Wizard of Oz the year before, the cheater won an oscar for The Life of Emile Zola, and the errand boy followed-up with Ford and Hitchcock movies.
